Transmission & ISOs

Arizona System Administrator. The Federal Energy Regulatory Commission told representatives of the Arizona Independent System Administrator that its proposed package of tariff and protocols was deficient, as it failed to show how Arizona Public Service and Tucson Electric (the ISA's two leading members) would amend their own open-access transmission tariffs (OATTs) to coordinate operations with the ISA.

Meanwhile, a group of irrigation districts in Arizona attacked the ISA plan, challenging the ISA's claim that it is exempt from filing its own OATT, and claiming that the ISA itself lacks legal standing, since local state court in Maricopa County last summer struck down the state PUC's entire regulatory scheme for electric deregulation (which included plans for the ISA), saying that the rules were never certified by the state attorney general.
